SUMMARY
A set is defined as bounded in the context of the Heine-Borel theorem if there exists a positive constant M such that for all elements x in the set S, the norm |x| is less than M. An equivalent definition states that a set has finite diameter, represented mathematically as diam(S) = sup_{x, y in S}(dist(x, y)). This definition is applicable to any metric space, although the Heine-Borel theorem itself is specific to subsets of Rn.
